Hi.
At this moment I have got a Nelson Pass Zen amp (first version). It sounds very good. I would like to bulid even better amp. I don't mind about the power, quality is most important. I like warm sound with forward midrange and nice deep bass. I would like SS amp not chip amp. I think a class A amp will be the best. I thought about: hiraga le monstre, jlh 1969, some aleph. What can you recomend?

Sorry if I made some lingual mistakes (I'm still practicing my english).
Greetings from Poland Oskar.

Did you know there is 9 version of the zen? The Aleph is an evolution of the zen.
Anyhow go for whatever looks good it's not an easy decision by any means.
I like the jlh but cannot compare it to the zen I'm still working on my zen 4.
I think if anyone builds an amp it should be class A since there are no commercial class A amps cheaply available.

First i thought about jlh 1969 because it's very simple and interesting amp and I can use cheap and good sounding old tesla transistors (kd502, kd503). But I have read somewhere that aleph is in the other league of sounding.
